Referring now to the drawings, 1 re rethe usual re vided on its outer periphery with longitudi- --nal extending ribs "4 the lower ends of which are to rest upon the upper ends of the ingot mold and support the feeder within the bore of the mold. In Fi ures 1, 2 and 3 of the drawings instead of" avin the ribs rstin per e go of the. mol

we have shown brio s 5 placed between the lower ends of the ribs 4 and the upper end of the mold. a

Our improved pouring pot consists of a metal receptacle 6 having an external bore to the internal bore of the feeder 3 and provided at its upper end with the annular flan e 7 adapted to rest on the upper edge of t e feeder 3. The fiangefl is provided with loops or books 8 by means of which the pot is handled in any desired manner.

drawings, the lower end of the pot 6 is provided with an inwardly extending flange 9, leaving the central opening 10 in the lower end of the pouring pot.

The pot 6 rests upon the flange 9 and said flange extending inwardly beyond the fire brick 11 and loosely fitting in the lower end of the pot and resting upon the flange 9 is the feedver plate 12 which closely fits against the fire. brick lining 11. This feeder plate 1s provided with a' series of .openings 13 extending vertically through and, through which the molten metal passes into the mold. -There may be any desired number of these openings as it has been found that by pouring the metal in small streams a perfect ingot is formed.

In the modification shown in F gure 3 of the drawings the pouring pot 6 has a solid bottom 14 provl ada ted to register with the o in the pouring plate. 1 n,t1us mo is lined with fire brick 11 which ded with openings 15 enings 13 xm and arranged exactly the same as that shown in Figure 2 of the drawings.

the pouring pot, fire brick are constructed In the modification shown in Figure 4 of the drawings, the feeder 3 has the ribs 4: resting directly upon the upper edge of the ingot mold 1. In this form the pourin pot 6 has a rounded lower end 16 provided with a series of openings 17 and resting in the lower rounded end of the pouring pot is the feeder plate 18 having opening 19 corresponding with the opening 17. In this form the tire brick 20 rests on and is supported by the upper edge of the feeder plate 18. a

In Figure 5 of the feeder 3 is arranged exactly the same, and the pouring pot 6 has its lower end tapering in all directions. These four tapering walls are provided with openings 22 and resting within the lower end of the pouring pot. is the pouring plate 23 having its four walls tapering corresponding with that of the pouring pot, ahd provided with opening 24 registering with the opening 22. In FigureftS of the draw-ings'the feeder 4 isarranged precisely the same as that 'shown in Figures 4 and 5 and the lower end of the pouring pot has two obliquely arranged walls 26 and 27 provided with 0 eni ng 28 and arranged in the lower end u the pouring pot are two pouring plates 29 and 30 meetingat the point 31 as shown in Figure 7. are covered by the bricks 31. as shown in Figure 6, and the fire brick lining 32 rests upon the upper end of the pouring plates 29 and 30 and the brick 31.

In Figure 8 the feeder 3, pouring plate 6 have fire brick 11 well constructed and arranged precisely like that, shown in Figure 2 of the drawings, instead of having the flat pouring plate 10, we have shown the semi-circular pouring plate 33 having the opening 34 arranged therein. In this The end walls of the bottom hiring a feeder extendin gure two modified forms of the pouring ates are shown as indicated at 34 and 35.

In Figure 9 the pouring plate 10 such as shown in Figure 2 of the drawings couldbe provided with elongated slots 36-instead of the opening 13. The same principle could be employed in any of the other'ones' comprising a metallic iugsupporting flange at its upper end, an"

in wardly extending flange at its lower end adapted to support a refractory lining.

3. In con'ibination with an ingot mold and a feeder supported within the upper end of the mold, of a pouring pot resting upon the upperend of the feeder and extending into the feeder, a removable pour-.

ing -plate in the lower end of the pot, and having a series of openings therein.

4. In combination with an ingot mold and a feeder supported within theupper end of the mold of a pouring pot su ported by the upper end of the feeder an having a the brick lining provided with a series of openings at its lower end.
